To provide a heat exchanger which improves a drain property of water residing between adjacent fins.SOLUTION: A heat exchanger is equipped with a tube 2 in which a refrigerant flows; a plurality of fins 3 aligned at intervals and provided integrally with the tube 2; and a drain pan 5. The drain pan 5 is installed under the plurality of fins 3 so as to collect water dropped from lower end portions 30 of the fins 3. At least a part of the lower edge portions 30 of te fins 3 comes close to an inner surface 50 of the drain pan 5 so that water adhered to the adjacent fin 3 and fin 3 can contact.SELECTED DRAWING: Figure 2 【課題】隣接するフィンとフィンの間に停留する水の排水性向上が図れる熱交換器を提供する。【解決手段】熱交換器は、内部を冷媒が流れるチューブ２と、間隔をあけて並びチューブ２と一体に設けられた複数のフィン３と、ドレンパン５と、を備える。ドレンパン５は、フィン３の下縁部３０から落下する水を回収可能なように複数のフィン３の下方に設置されている。フィン３の下縁部３０の少なくとも一部は、ドレンパン５の内表面５０に対して、隣接するフィン３とフィン３とに付着している水が接触可能な程度に近接している。【選択図】図２
